SULKY-PLOW.

SPECIFICATION forming part of Letters Patent No. 782,187, dated February 7, 1905.-

Application filed February 24, 1904. serial No. 195,070.

To (all (I /111111, it many (lo/warn:

Be itknown that I, \VILLLiM ALBERT BALD- WIN, a subject of the King of Great Britain, residing at Smiths Falls,in the county of Lanark, Province of Ontario, Canada, have invented certain new and useful Improvements in Snlky-Plows: and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to plows of the type called sulky or riding plows, wherein the machine is carried entirely on wheels and adjustments are provided for shifting the plowshare vertically and horizontally with respect to the wheels.

The object of my invention is to improve this type of plow by providing certain additional and novel adjustments which give it a greater flexibility and, furthermore, by improving the arrangement and collocation of the parts.

One of the main features of my improved plow resides in an adjustable mounting in the rear end of the plow-beam, which is mounted to slide vertically with respect to the pedestal which supports the rear wheel, and a gearsegment engaging with a rack on said pedestal is provided in connection with a hand-lever whereby the share is raised and lowered with respect to the rear wheel, this being used in conjunction with a vertical adjustment of the front end of the beam, so as to keep the plowshare at all times level and prevent its nose from dipping into the ground. This feature is intended especially for giving the plowshare a large range of vertical adjustment, so as to enable it to be raised in some instances entirely off the ground.

My invention comprises further improvements in the form and arrangement of the steering-rod by which the rear wheel is joined to the front axle in this type of plow.

My invention further comprises other features, which will be hereinafter more particularly referred to, and pointed out in the claims.

In the drawings accompanying this specification 1 have shown one embodiment of my invention, wherein Figure 1 is a side elevation of a plow embodying my improvements. Fig. 2 is a plan view thereof; and Fig. 3 isa plan view, on an enlarged scale, of the rear end of the plow beam and pedestal.

The plow beam is designated by the numeral and carries the standard 5, to which is secured the share 6, carrying the moldboard T, the landside being preferably omitted in this plow, as its place is supplied by the steering-wheel or rolling landsidc 8. The front end of the beam is carried by two wheels 9 and 10, which are journalcd on stub-axles 11, secured to the ends of rock-arms 12 13, the former secured rigidly on the transverse rocking axle H, and the arm 13 is loosely mounted thereon and adjustable about the axle by means of a hand-lever 15, having a linger-lever 16, the bolt 17 of which engages with the notched quadrant 18 on the hub 19, lixcd to the axle 1d. On the axle ii is also slidably mounted a yoke 20, having cars 21, to which is secured, by means of a bolt 22, the clips 23 of the pole 2%. On the axle 14:, at about its center, is rigidly fixed a lever-arm 25, and at the base of this arm is provided an eye 26, forming a point of connection for a link 27, pivotally connected at its other end to a hand-lever 28, which is mounted on a pivot-pin 29 transverse to the axle in an extension-lug 30, formed at one side of the yoke 20, and provided with a notched quadrant 31, with which engages the bolt of the linger-lever 32, this arrangement enabling the yoke 20 to be slidably :uljustcd on the main axle 'l-l.

At about the center of the yoke 20 is pivotally connected the forward end of the beam 4 by means of clips 33 and a king-bolt 34:, passing through the yoke. The lower end of the king-b lt also forms a point of attachment for the draft mechanism, comprising a draw-bar 35, forked at its forward'cnd and carrying any suitable draft appliance, such as a doubletree 36 andswingletrees 37, if a twohorse draft is desired. This arrangement is novel in that it enables the draft to be applied directly to the end of the beam, and hence always in line with the resistance of the plowshare, instead of to the axle 1%, as heretofore. There is also mounted upon the beam 4 of the plow a disk colter 38, suspended in line with and in proximity to the cutting edge of the share, and, as shown, it is journaled in a me tallic fork 39, Whose upper end is provided with a socket 40, in which is fixed the curved rod 41, whose upper end is vertical and is adjustably'secured to the beam by a clip 42.

The rear end of the beam 4 does not, as heretofore, rest directly upon the rear wheel 8 of the plow; but it is connected therewith by a novel adjustment. This wheel is journaled at the lower end of a post 43, which is vertically swiveled in the pedestal-block 44 at its upper end. This pedestal-block, which projects forwardly, has in its front edge a T- shaped groove 45, and the standard 5, which is bolted to the rear end of the plow at 46 by means of a horizontal extension thereon, has a vertical T-shaped head or flange 48, adapted to slide in the groove 45. At one side of the groove 45 on the pedestal-block 44 is formed a rack 49, with which engages a gear-segment 50, cast on the pivoted end of the hand-lever 51, which is fulcrumed on a pin 52, forming one of the bolts by which the standard is secured to the beam, as shown in Fig. 3. The outer end of the bolt 52 passes through a stationary block 53, bolted to the right side of the beam and which carries the notched quadrant 54, engaged by the bolt 55 on a fingerlever 56, carried by the hand-lever 51, and the latter has preferably a flange 57 overhanging the edge of the segment 54, which serves as a support against lateral movement. The lever 51 is also connected to the rock-lever 25 by a link 58, secured to the shank of the hand-lever.

It will be seen that the lever 51 is so connected to the front and rear wheels as to raise and lower the plow-beam 4 horizontally, because when the lever is, for instance, pushed forward the gear-segment 50 is lowered upon the pedestal-block 44, lowering the rear end of the plow, and simultaneously the axle 14 is rocked so as to oscillate the wheel-arms 12 and 13 rearwardly, thus lowering the front end of the beam, and the reverse when the lever 51 is drawn back.

Another important feature of my improved plow resides in the adjustability of the steering-wheel connection, which in this plow comprises arod 59, pivoted at its front end to the car 60 on the yoke 20. The post 43 of the rear wheel has on its upper end, as usual, a lever-arm 61, extending to the opposite side of the beam 4 from the ear 60. In former plows of this type the bar 59 was connected directly to the end of this lever 61, passing diagonally across the beam. In my present plow, however, it is extended parallel to the beam, and thus is out of the way of the seatpost and other parts fixed to the beam and at the same time has an adjustable connection with the lever 61 by means of a bar 62, pivoted on a pin 63 at the end of the lever 61 and bifurcated at its opposite end 64, which is bored to receive the end of the rod 59. The latter is threaded, as shown at 65, and has mounted thereon in the recess 66 of the bifurcated end 64 a nut 67, by adjust ing which on the rod 59 its active length is varied. The front bifurcation of the end of the bar 62 is also provided with recurved lugs 68 69, which embrace the flange 70 on the hub of a locking-block 71, loosely mounted on the rod 59, and thus held in operative relation with the bar 62. The free end of the block is formed to abut against the rear face of the upstanding portion 72 of the pedestal-block, in which the groove 45 is formed, this abutment taking place when the steering-wheel 8 is accurately in line with the beam, so that the Wheel is absolutely prevented from being thrown out of line by the pressure of the land or sidewise effort of the share, as it might otherwise do by reason of the bending of the rod 59. The locking-block 71 may also have a small snug 73 forged thereon, which forms a rest to support the'block against the lug 69 when it is thrown over out of contact with the pedestal-block, as when it is desired to turn the plow or shift it laterally, so as to prevent the block 71 from falling completely over.

The seat of the driver (designated 74) is preferably mounted on a post 75, secured to the side of the pedestal-block 44, and the locking-block 71 is readily manipulated by the driver from his seat, as well as the various adjusting-levers 15, 28, and 51.

Scrapers 76 and 77 are shown as applied to the colter 38 and rear wheel 8, respectively; but these form no part of the present invention.

IVhile I have shown in the accompanying drawings the preferred form of my invention, it will be understood that I do not limit myself to the precise form shown, for many of the details may be changed in form or position without affecting the operativeness or utility of my invention, and I therefore reserve the right to make all such modifications as are included within the scope of the following claims or of mechanical equivalents to the structures set forth.
